1) How we got here:
The polls always showed that Trump would beat Clinton and lose to Sanders. The DNC chose to win the wrong battle.
2) Where we go next:
Trump’s only consistency is to say whatever the voters want to hear next. He can say “A is best” on Monday and “A is worst” on Tuesday and his supporters will cheer him both times.
There is little point trying to predict what he will do once he is president. There will be no consistent plan, unless he becomes a mouthpiece/figurehead for others. Only time will tell.
His track record in business is to lose in negotiations.
3) What to do about it:
Centre and ground. Know what is most important to you and how you are going to get it. Realise that if Clinton were president you would still have faced challenges. With Trump they will be different challenges. Given his inconsistency, volatility, there are also likely to be more challenges. But that doesn’t change what you want, it only changes how you get there.
